Step 1:

\

Complex zeros of cubic function \"\" and \"image\"-intercept is \"\"

\

Zeros are \"\" and \"\"

\

By using Factor theorem,

\

When \"image\" then \"image\" is factor of polynomial.

\

\"\"

\

\"\"

\

\"\"

\

Apply the formula \"image\".

\

\"\"

\

\"\"

\

\"\"

\

\"\"

\

\"\"

\

Solution:

\

Cubic polynomial function is \"\".
